Cooke S4/i Mini (Uncoated) Set of 6 (18mm, 25, 32, 50, 75, 100)

The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.

/i Electronics

A cable connector near the lens mount and contacts in the mount sync with /i compatible cameras and accessories.

Color Balance

All Panchro prime lenses are color balanced to a specification within parameters approved by Kodak.

Aperture

All Panchro primes have a true T2.8 aperture and cover Super 35mm format.

Index Marks

Every index mark is labeled. More detailed markings allow for more detailed focus control.

Focus Movement

Our Academy Award-winning cam-style focus movement, coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus. Spherical aberration has been controled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth, positive, backlash-free movement.

Focus Scaling

Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.

Compatibility

All Cooke Panchro primes have a common fixed front diameter of 87mm, with a focus drive gear of 121T x 0.8 mod and an iris drive gear of 119T x 0.8.

External Finish

A scratch resistant PTFE hard anodized finish is provided on all Cooke lenses, providing a durable, hard-wearing surface to meet the most demanding environmental conditions.

Iris

An eight-leaf linear module iris assembly is fitted into Panchro primes with an aperture range of T2.8 to T22.

Weight/Size Ratio

These lenses are designed for all shooting applications, including handheld and Steadicam, providing a comfortable balance ratio with the latest compact cameras.

Panchro prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
